Simulate the sound of subatomic particles

Great scientists Hadron Collider (LHC) in the French-Swiss developed a way to convert to sound the collision of subatomic particles. Now they hope with this method to detect the elusive, hypothetical Higgs boson, the so-called God particle.

The Higgs has never been seen but if there could explain the origin of the mass of other elementary particles and answer many questions about the origin of the universe.
The LHC - the largest particle accelerator in the world - are conducting experiments in which tiny particles are made to move in opposite directions simultaneously in the tunnel 27 kilometers in diameter.

The aim is to produce a collision of particles to recreate conditions that occurred just after the Big Bang.

Dr. Lily Asquith, who conducted the data model in the LHC experiment, worked with sound engineers to convert the data expected from the collisions of sounds. "If the energy is near you will hear a pitch low and away from you if you hear a high pitched" the scientist told the BBC.

"If it comes to large amounts of energy will be much stronger and if the tone is little power will be weaker," he adds.

In the LHC's circular tunnel, there are thousands of magnets that guide the proton beams of particles around the big "ring." At certain points around the tunnel, the beams intersect and collide with each other about four "subexperimentos" massive monitor these collisions.

Scientists hope that in these collisions emergence of new subatomic particles, which could reveal new information on the origin of the cosmos.

In one such experiment, called Atlas, was carried out the measurement of sound.

Within it is an instrument, the calorimeter, which is used to measure the energy and consists of seven concentric layers. Each layer is represented by a note and tone of each of these differs from the amount of energy that is deposited in that layer.
So far Dr. Asquith and her team have generated a number of simulations based on predictions of what might occur during collisions in the LHC.

"When you hear what they really are listening to the sonificaciones scientific data. These are authentic, and you are saying something about the data that might not otherwise know," said Archer Endrich, a software engineer working on the project.

The aim is to provide physicists another way to analyze LHC data. The team believes that the sonification ears are better adapted to the eye to detect subtle changes that might indicate the presence of a new particle.

Richard Dobson, a composer who is also involved in the project, said he was surprised by the musical sound of the collision.

'We can hear the sound structures, clear, almost as if they were composed.

"They seem to tell a story. Not very dynamic and change all the time, and they sound like music we hear in contemporary compositions," he adds.
Although the project is intended to provide particle physicists a new tool of analysis, Endrich Archer believes this could also be allowed to hear the background harmonics in the universe.

The scientist hopes that the particle collisions reveal "something new and something important about the nature of the universe."
